The test was conducted on 3D printed test samples made according to the ISO 527-2 standard. The samples are made of HI-PLA (High Impact Polylactide) polymer material with pronounced resistance to impact toughness and it is closer, according to its characteristics, to ABS material. The test samples were printed by FDM additive technology with different layer thickness and material filling percentage, and a central composite test plan was carried out. The conducted experiment resulted in stress-strain diagrams for 11 states of the test samples, on the basis of which the tensile strength of the HI-PLA material was calculated. The obtained values ​​were compared with the tensile strength values ​​for ABS material.","PeriodicalId":388226,"journal":{"name":"Technium: Romanian Journal of Applied Sciences and Technology","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115967397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, this study mainly highlights the need for integrating technology in the classroom, for example, using computer-based learning and networks and communications systems to support learning. In this way, classroom interaction can offer a new way for students to interact and engage with course materials. Furthermore, this study aimed to determine the students’ prior knowledge of technology in learning English, including their interests and usage; our findings also discuss how lecturers integrate technology in the classroom. This study used a descriptive quantitative method, with respondents including 60 students and 8 lecturers. The results of the research describe the students’ prior knowledge, the interest and use of technology in learning English, as well as the integration of technology used by the lecturers in classroom interaction. It can be concluded that most students and lecturers are not that all familiar with the 14 kinds of technology that are commonly used for English learning.","PeriodicalId":388226,"journal":{"name":"Technium: Romanian Journal of Applied Sciences and Technology","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127607838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the catches in Rembang waters which is quite high is the squid fishery which landed at PPP Tasik Agung. The most common types of squid landed at PPP Tasik Agung are Loligo chinensis, Loligo duvaucelli, and Loligo edulis. The purpose of this research is to know the biological condition of squid, the condition of capture fisheries, and to know the management that can be done. The study was conducted from June to July 2022. Random sampling method is the method used in sampling. Analysis of the data used is the relationship between length and weight, sex ratio, gonad maturity level, size at first caught and mature (Lc and Lm), and EAFM domain of fish resources. The results showed that the capture of squid is still not well controlled. The results of the t-test measuring the length-weight relationship of the three species that have been found indicate that the growth is allometric negative. As many as 49.6% of the three types of squid that have been caught are indicated to be immature gonads because they have been dominated by TKG I and II. The ratio of male and female sex of all samples is 1: 0.54. The overall composite indicator assessment result on the fish resource domain indicator is 0.48 (48%). One of the strategies in the management of squid fisheries that can be done is to make regulations for limiting fishing efforts and the minimum size of fish that can be caught.\u0000 \u0000","PeriodicalId":388226,"journal":{"name":"Technium: Romanian Journal of Applied Sciences and Technology","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125043252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly, the study sought to present an in-depth and inclusive discussion about the traditional media and social media, focusing on the challenges and opportunities of each type. It is worth mentioning that the present study adopted the Semi-Systematic Review Approach through which the findings of a sample of studies that are consistent and similar to the current study’s topic have been identified, selected, assessed, synthesized and summarized in an explicit and planned manner which eventually led to allow the researcher to make inferences based on analyzing the resulting summary indicated in advance. The findings of the data analysis demonstrated that the traditional media and the social media have their pros and cons. Additionally, there are major differences between the two types, including: while traditional media generally offers a wider audience pool, social media allows for more targeted distribution; social media is immediate, while traditional can be delayed due to press times; traditional media pieces are more final, where social media is dynamic; social media offers more control over the message than traditional media; social media is a two-way conversation, and traditional is one-way, i.e., with social media, the public has the opportunity to voice their opinions. Furthermore, the findings of the study revealed that although social media has become the most convenient and prevalent communication channel with the ability to reach a broader audience, and although the rise of new media, particularly social media, has put a danger to the survival of some traditional media outlets and reduced their readership and viewership, however traditional media, which is no longer as dominant as it once was, is still a relevant source of information for society and a wide audience who are looking for the credibility and reliability of the news that is circulated on social media. Finally, the study concluded that despite the fact that traditional media and social media both have their pros and cons, however the relationship between them is still a relationship of integration, not a relationship of exclusion or cancellation. Thus, instead of being pitted against one another, traditional and social media outlets can go hand-in-hand through developing a successful integration, a complementary relationship, and a sustainable sharing processes between the traditional media and the social media outlets in a collaborative, cohesive, and in an ethical manner, as such integration would enhance their roles and services, provide added values than ever, and enable them to reach the widest amount of people at an effective frequency and deliver –in record time and without interference- an easily accessible content that is more interesting and present such content in an attractive ","PeriodicalId":388226,"journal":{"name":"Technium: Romanian Journal of Applied Sciences and Technology","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114168152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
